Patented ire-nac, reir.

Application filed April l?, 1916. Serial No. 91,789.

New York, have invented a new and useful MechanicalMovement, of whichthe ollowing is a specification.

The'main object of my-invention is to provide a mechanical movementoflsimple con struction in which the driving member actu ates the drivenmember with a quick snap movement.

One feature of-my invention consists in a longitudinally moving drivingmember for accomplishing this object and in'the preferred form I providea rocking member and an actuator for. the rocking member, said actuatorbeing put in position for actuation by means of a spring.

Another' feature consists in means movable in the same direction toactuate the rocker in different directions.

`Other features of my invention will be pointed out below.

In the drawings:

Figure `l lis an elevation of ',anelectric switch embodying myinvention; l

Fig. 2 is an elevation partly in section at a. right angle to theposition of Fig. l;

Fig. 3 is a. plan of the switch of Fig. 2;

Fig. 4 is a fragmentary section of the bridging memberon the line 4-4 ofFig. 3; and

Fig. 5 is a section on line 5`5 of Fig. 8, with certain portions of theswitch omitted.

In the drawings I show my'invention enr bodied in an electric switch.

Base portion A of insulating material is connected by screw a withcenter contact c', the latter beinO' extended vertically to form amoving conductor a2. A similar moving conductor a is connected by screwa4 to the other side of base portion A.

Frame member B of insulating material isnotched at b b and in notch b isconductor B in sliding engagement with conductor ai?, the upper portionof conductor B extending partly across the top ofmember B and heldthereto by screw^D. The vconductm' B slotted at b2 to receive conductora. and has y B2 is slotted at 7) to slidingly engage conductor a2 andhas' a. pocket for coiled spring if which engages plunger Z13 and tendsto press members A and B apart. Conductor B2 is held to member B byscrew b9 and carries binding screw 7210.

Supporting yoke E and limiting yoke E are held to member' B by screw c.Rocker F has'a shaft f whose end bearings are in yoke E, the shaft fhaving an neccentric portion f 'to which is connected oneY end of coiledspring f2, the other end being connected by eye f3 to the bridgingmember Grl which is` also pivoted on shaft f. The limiting yoke- E" isengaged by the portion fso that 'the latter can not' oscillate beyond a.certain limit in either direction.

Pivoted at g to member A i's operating lever G", slotted at g andcarrying ping/2 whichrides in the slot f4 of rocker F, the

slot g engaging one end of spring H which extends around screw t andacross' member Gr and into aperture i1. so that thespring H anchoredagainstl turning, the screw when screwed in, aiding in holding thespring in place. y

'Member G bridges the two contacts KK', contact K and metal washer Itbeing held in position by screw D. Contact K is held in place by screw7c which also holds plate 7a2 in position, 'plate 7a2 carrying bindingpostc.

The circuit is through binding post 7c3, contact K', member G, contact`K, screw D, members B and a3, screw c4, shell a5, the lamp or otherelectrical appliance l(not shown), center contact a', members c2 and B2and binding post Z210.

I preferably -provide a tubular insulating covering o of fiber or thelike outside the screw shell a5 and my whole dei/ice may be housed inany suitable casing such as a shell and cap. f

The screw shell a5 is a support for the sov lamp or other electricalappliance that may be used and with the members a and a.

moves longitudinally with relationv to memsupport inward. or toward theswitch mechanlsm pro-per. thc first effect being that pin g2 rides'tothe right in slot f4 and lifts the right end of rocker F carrying withit the. end ff of spring f2 land when this end has passed the lineextending from f3 through )ivot i the s iii-infy which has been ex)anded will be free to contract and swing bridging member (i on itspivot until its left end is vwill press members A and B apart, theseparation beinglimited by in g2 engaging the lowest part of slot f5 Itis to be observed that' if pin g2 Were at rest immediately'beneath pivotf then it would be difficult to press the shell ainwardly so' I pro--vide spring H toswing lever G slightly to one side orthe other of thedead center inl order that pinA g2 .may move freely in slot f4 whentheoperationis started. In the posi-- tion shown that end of thespring Hwhich is attached by screvi7 i to member G" is, as compared Witlitheother position of' oscillation of member G, relatively removed from slot-g and therefore the tendency is to pull the fr'ee end of spring Htoward the right with the consequence that ping2 rests slightly to theright of the dead center. When however, the left end of the bridgingmember G has been raised to make the circuit that end ofspring H whichis fixed to g so that When the shell a5 is moved out- Wardly springHwill tend to expandand therefore push lever G slightly to the left ofthe dead center and pin g2 will therefore be ready on` the neXtoperation to lift the left end of the rocker F which ivill lower the endf5 of spring f2 so as to break the circuit and this movement will returnthe parts to the position shown, spring H having acted to pull lever Gslightly to the right-of the dead center.

What I claim is:

`l. A mechanical movement comprising a pivoted driven member extendingon both sides of its pivot; a driving member to engage said drivenmember alternately' at opposite sides of the pivot of said drivenmember; and positive means separate from the driven member acting toinove said driving member away from its central position to accomplishsuch alternate engagement.

2. A mechanical movement comprising a pivoted driven member; a piyoteddriving member to engage-directly said driven member, the pivot-of saiddriving member being movable; and a spring to shift said driving memberfrom its central position so that it Will eiigage said drivenVmemberalternately at opposite sides of the pivot of said driven member.

3. A mechanical movementcomprising a engagement.

A mechanical movementcomprising a pivoted, driven member; a pivoted driving member to engagesaid driven member alter- -nately at opposite sides of the`pivot of saiddriven member, the ivot of said driving member being movab e; andaspring actuated bythe driven member to swing lsaid driving member onits pivot.

6. A mechanical movement comprising a rocker; a lever mountedl to movebodily to- Ward and from said rocker and operating to shiftl said rockeralternately in opposite directions; and means movedby the rocker andmoving to shiftA the lever from its central position to cause the leverto shift the rocker alternately in opposite directions. w 7.
